Description: A biometric token is a physical device that uses biometric data, such as fingerprints, facial recognition, or iris scanning, to authenticate a user. These devices are integral to multifactor authentication systems, as they combine something the user has (the token) with something the user is (their biometric traits). The main feature of biometric tokens is their ability to provide a higher level of security than traditional passwords, as biometric data is unique to each individual and difficult to replicate. Additionally, these devices are often compact and portable, making them easy to use in various applications, from accessing personal devices to security systems in diverse environments. The relevance of biometric tokens has grown in a world where data protection and identity management are crucial, offering an effective solution to mitigate the risk of unauthorized access and fraud. Their implementation has been favored by the increasing acceptance of biometrics as a reliable and convenient method for user authentication across multiple platforms and services.
History: The use of biometrics for authentication dates back to the late 19th century when fingerprints were first used in the judicial system. However, biometric tokens as physical devices began to be developed in the 1990s, with advancements in biometric scanning and data processing technology. As technology has evolved, biometric tokens have become more sophisticated and accessible, integrating into various devices and security systems.
Uses: Biometric tokens are used in a variety of applications, including access to mobile devices, access control systems in buildings, authentication at ATMs, and in corporate environments to protect sensitive information. They are also used in identity verification at airports and in public security systems.
Examples: Examples of biometric tokens include fingerprint readers on smartphones, facial recognition systems on laptops, and iris scanning devices used in high-security facilities.
